    Yeah something in the serpentine system.

    Honestly I can't hear much beyond a failing bearing and power steering. Time to run it without the belt and start hand spinning pulleys. Or maybe get lucky with a stethoscope.

    The power steering pump on your car is known to whine, even when brand new. Just keep that in mind.

    Do you guys think that's where the noise is coming from?

    No, but trying get to diagnose bearing noise via video in the serpentine system isn't effective. I posted a video similar last year with no luck. You really just got to take the belt off or stethoscope it.

    How do you do that and what does stethoscopeing it do?

    Pulling the belt off is a matter of putting a socket on the tensioner, pulling it to the side, and removing the belt. Then you individually turn all of the pulleys and see if any of them are making any sort of grinding noise or feel like they are hanging up.

    Power steering will be a little difficult to spin by hand because you will be manipulating a pump that is already pretty poorly designed and noisy. Like I already said.

    The crank pulley will also be difficult to turn because you would be spinning the entire motor, I actually recommend not doing that. What you really need to worry about are the idler pulleys (not hooked up to anything), the tensioner pulley (the one on the tensioner, go figure), the water pump pulley (which again may be tough to manipulate but it's typically quite easy) and the alternator.

    A mechanic's stethoscope can sometimes tell you things, but I feel like sometimes it is also very hard to hear over the motor. Plus someone newer using a stethoscope on a running motor might get caught up, and we certainly don't want you getting hurt. This is from my own dumb experience getting burned pretty good on a moving belt.

    If I do find where the squeaking is coming from I feel like it is the belt or on of the circle things (so sorry for calling it that :( ) what do I do then?

    The "circle things" are pulleys. And if one of them is causing the trouble, you change it. Most of them can be changed in minutes. If it's the belt, change it. It takes minutes, but typically the belt doesn't make much noise.

    And where can you get pulleys from?

    Mine had a bearing seized on a supercharger pulley, so no relevant to your dilemma.

    If you have a good mechanic any way you shake a stick at it a serpentine pulley is usually a repair under $200 dollars.

    However your experience may vary!

    The circle thing change out only takes ten mins.

    I got my power steeri fixed today so that's not making noise anymore yay :) but the noise that's in the video is the cam synchronizer. How important is this or could it wait a couple weeks?

    Cam synchronizer? Elaborate please.
